3. White Platen Roller
This option is used to make the back-
ground color to be white. Two white platen
rollers are in a set. The background color will
be white by replacing the normal black platen
rollers to white platen rollers.
For the replacing procedure, refer to the
items of the Platen Lower Roller and Platen
Upper Roller in the "Chapter 3 DISASSEM-
BLY & REASSEMBLY". Only the color of
roller is different. Both of lower and upper
rollers have to be replaced.
After replacing, you don't need any set-
tings or adjustments. The scanner automati-
cally detects that the background is white.
However, a part of functions for the im-
age processing becomes unavailable be-
cause of the white background. Those limita-
tions are shown below.
 Auto size detection
 Deskew
 Folio (Folded document scanning)
 Black frame removal
 Black hole removal
